Within this framework, CAPs act as non-Hermitian reservoirs and sinks, enabling an effective assessment of transport efficiency. We apply this approach to cyanine dye aggregates to examine how vacancy defects and system size influence exciton transport in two-dimensional sheets and quasi-one-dimensional tubes. We further introduce a CAP-based classification scheme that links molecular packing in two-dimensional aggregates to their transport behavior. Our results demonstrate how aggregate topology and structural disorder govern exciton transport and provide design principles for developing materials with enhanced energy transport.<\/jats:p>","DOI":"10.1063\/5.0344077","type":"journal-article","created":{"date-parts":[[2026,8,17]],"date-time":"2026-08-17T17:53:45Z","timestamp":1786989225000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Simulating exciton transport with complex absorbing potentials"],"prefix":"10.1063","volume":"165","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-8769-2645","authenticated-orcid":false,"given":"Dimitri","family":"Bazile","sequence":"first","affiliation":[{"name":"Department of Chemistry and Biochemistry, University of California, Los Angeles 1 , Los Angeles, California 90095,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5126-3829","authenticated-orcid":false,"given":"Justin","family":"Caram","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biochemistry, University of California, Los Angeles 1 , Los Angeles, California 90095,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9262-1880","authenticated-orcid":false,"given":"Chern","family":"Chuang","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biochemistry, University of Nevada 2 , Las Vegas, Nevada 89154,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3160-386X","authenticated-orcid":false,"given":"Daniel","family":"Neuhauser","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biochemistry, University of California, Los Angeles 1 , Los Angeles, California 90095,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2026,8,17]]},"reference":[{"key":"2026081713533995100_c1","doi-asserted-by":"publisher","first-page":"1700236","DOI":"10.1002\/aenm.201700236","article-title":"Exciton transport in molecular aggregates\u2014From natural antennas to synthetic chromophore systems","volume":"7","year":"2017","journal-title":"Adv.
